Embodiment Construction

[0012] Figure 2-4 Shown is the first embodiment of the present invention, which includes a lock body 1 and a lock cylinder 2. There are several blade grooves in the lock cylinder 2 along the axial direction, and the built-in blade 4 is at a position perpendicular to the blade grooves. There is a lock pin groove along the axial direction, and the built-in lock pin 7 and its spring 73 are arranged on the long side corresponding to the leaf 4 and the lock pin 7. shaped groove 41, several small interference grooves 5 are arranged on the other long side of the leaf 4; an interference pin groove is opened in the axial direction at the position corresponding to the interference groove 5 of the lock cylinder, and the interference pin 11 and its spring are built in 12. The inner end surface 111 of the interfering pin 11 matches the interfering groove 5; on the lock body, there is a locking groove 8 at a position corresponding to the locking pin.

Abstract

An elastic force interfered blade lock head comprises a lock body and a lock cylinder. The lock cylinder is provided with a plurality of blade grooves, blades are arranged in the blade grooves, a lock pin groove is formed in the position perpendicular to the blade grooves in the axial direction, a lock pin and a spring thereof are arranged in the lock pin groove, one long side, corresponding to the lock pin, of each blade is provided with an isosceles trapezoid groove, and the other side of each blade is provided with a plurality of small interference grooves. An interference pin groove is formed in the position, corresponding to the interference grooves of the blades, of the lock cylinder in the axial direction, and an interference pin and a spring thereof are arranged in the interference pin groove. A locking groove is formed in the position, corresponding to the lock pin, of the lock body. After the technical scheme is adopted, during technical unlocking, the inner end face of the interference pin enters the interference groove of each blade, and under the interference of the interference pin, technical unlocking is hard to achieve.

Description

technical field [0001] The present invention relates to a kind of lock, more specifically, it relates to a kind of lock head. Background technique [0002] The patent No. ZL 200720062590.6 is a patent titled "An Anti-theft Leaf Lock and Key". Its structure and principle are that there are Shaped grooves, through these grooves to control the locking and opening of the lock pin, its anti-technical opening performance has been improved to a certain extent, but the unlocking technology is also developing by leaps and bounds, and now the lock with this structure is easy to be used. Technology turned on. Contents of the invention [0003] In order to overcome the shortcoming of above-mentioned patent, the present invention provides a kind of locking end that strengthens anti-technical opening performance. [0004] The present invention is realized in the following way: comprising a lock body and a lock cylinder, a plurality of blade grooves are arranged in the lock cylinder a...
